A lot of guys RTV and it seals up. The sump bolts can and sometimes do come loose so they might only need a tighten up. Give it a big clean, retorque the sump bolts and see if it leaks and where it's doing it. Check the timing cover bolts - see if any have torqued themselves loose. If you need to change the front crank seal, this isn't a deal breaker. You can remove and install it without taking the engine out. The trick is installing the replacement without damaging it (or gouging the crank) If you are patient, use a cork gasket sheet. It is superior to paper gasket material. You will need a brand new hole punch and a really sharp fresh blade to cut it to shape.
